PAIS

This register allows insertion of path level alarms and diagnostic signals.

PAIS:

The PAIS bit controls the insertion of STS path alarm indication signal. When a

logic one is written to this bit position, the complete SPE, and the pointer bytes

(H1, H2, and H3) are overwritten with the all ones pattern. When a logic zero is

written to this bit position, the pointer bytes and the SPE are processed normally.

DB3:

The DB3 bit controls the inversion of the B3 byte value. When a logic zero is

written to this bit position, the B3 byte is transmitted uncorrupted. When a logic

one is written to this bit position, the B3 byte is inverted, causing the insertion of

eight path BIP-8 errors per frame.

Reserved:

The reserved bits must be programmed to logic zero for proper operation.
